| prekallikrein | <chemical> A plasma protein which is the precursor of kallikrein. Plasma that is deficient in prekallikrein has been found to be abnormal in thromboplastin formation, kinin generation, evolution of a permeability globulin, and plasmin formation. The absence of prekallikrein in plasma leads to fletcher factor deficiency, a congenital disease. Chemical name: Kallikreinogen (12 Dec 1998) |
